When a check valve is not installed on your sump pump’s discharge line, a back flow of water can cause the pump impeller to rotate backwards and unscrew off the motor shaft. If this occurs, the motor in your sump pump will sound like it is running but it will not be pumping any water out the discharge line.
How do I know if check valve is bad?
Symptoms of a Failing Check Valve
For example, failing check valves will start to vibrate and even lose some internal parts when problems begin to arise. Other symptoms of check valve failure include reverse flow and excessive component wear and damage. Check valves will also emit noises as they start to break down.
How long does a sump pump check valve last?
It’s a difficult question to answer because every system will have some differences. Typically, our valves will last in an excess of 5 to 7 years, so we recommend replacing it that often. However, if the pump cycles frequently, that can result in the check valve wearing out faster than that.
How much does it cost to replace a sump pump check valve?
The average cost to replace a sump pump check valve is $15 to $30 for just the parts. A check valve is installed to prevent water from flowing back into your sump basin when your pump is off.
How often should a sump pump check valve be replaced?
On average, sump pumps need to be replaced every 7 to 10 years.
What happens if the check valve goes bad?
For example, check valves that are starting to fail will vibrate or make a noise indicating that the valve has broken. A strange noise can also be a sign of ‘water hammer’ which is a high-pressure surge that occurs when the fluid comes to a stop or changes direction, often causing the disc to slam into the valve.
Do I need a check valve on sump pump?
Sump pump check valves are an important part of any sump pump system. Installed in the discharge pipe leaving your sump pump, the sump check valve prevents your pump from having to re-pump water it has already discharged.
How often do check valves fail?
While typical component lifespans are application specific, manufacturers suggest metal and plastic check valves should be replace every 5-7 years whereas check valves manufactured from rubber may remain fully serviceable for up to 35-50 years.
How many years does a sump pump last?
How Long Does A Sump Pump Last On Average? Like other appliances and equipment in your home, your sump pump won’t last forever. Averaging about 10 years, you might not notice your sump pump has malfunctioned until it has stopped working.
Is a check valve necessary?
Check valves are an important component of every submersible pump water system. Why are check valves important? First, they allow your water system to maintain pressure when the pump shuts off. They also prevent backspin, up thrust and help minimize water hammer (more on this later!).
How much does it cost to replace a check valve?
Depending on the size of the system and how much it costs, most homeowners pay between $135 and $1,000. The device costs between $35 and $600, while labor costs between $100 and $400. You can expect to pay between $70 and $250 for a back water or check valve.
Why is my sump pump check valve so loud?
If you hear a loud noise every time you pump stops, you have a Standard Check Valve installed. That noise is the check valve closing which creates a slamming effect when the water flow reverses in the discharge pipe after the pump stops.

What causes sump pump failure?
The most common reason for sump pump failure is an electrical power outage as a result of bad weather or a storm. Sump pumps depend on your home for power and these blackouts can be problematic. Because power outages happen at random, the best way to combat this is by having a backup generator.
How do you clear a sump pump blockage?
Avoid pulling up on the float switch or power cord. Remove the drain pipe by loosening the clamps that attach the pipe to the sump pump. Use a plumber snake or a metal hanger wire to push any blockage through the pipe. Use a hose (higher pressure, if possible) to flush the pipe and clean the inside walls.
